How do I get the Hyper Pixel 4 and Raspberry Pi model 4 (4 GB) to work together. It worked once until i rebooted and now there is nothing! have reinstalled everything again and still nothing.
Raspberry Pi 4
Again, It worked once until I rebooted and then the screen was black and no back lights. Redone everything I had done for it to work the first time and still no change. BLACK SCREEN.
It did the same on pi 400. Worked until reboot than blank screen.
I also seen several comments in the pimoroni forums many people are dealing with dead hyper pixel displays!!
What changes have you made to /boot/config.txt?
I’ve been round the houses with this screen recently, in the end I managed to decipher this post:

:warning: PSA: Make sure you disable i2c, SPI and any other interfaces since the… se will cause a conflict in device-tree with HyperPixel :warning:
:warning: A fresh image is recommended, but otherwise make sure you also disable the `hyperpixel4-init` system service! :warning:
Pi 3B and Pi 4 users running the latest and greatest Raspberry Pi OS should forego our installer and use the instructions below.
> :information_source: If you're tied to an older OS and you want to install the legacy drivers, use:

This new OS can currently be found in Raspberry Pi Imager under "Raspberry Pi OS (Other)"
Once installed you need only one line in `/boot/config.txt`:
* Rectangular: `dtoverlay=vc4-kms-dpi-hyperpixel4`
* Square: `dtoverlay=vc4-kms-dpi-hyperpixel4sq`
You can rotate these in config.txt by adding the `rotate=` parameter, like so:
```
dtoverlay=vc4-kms-dpi-hyperpixel4sq,rotate=90
```
This supports rotation in console, too, for all you CyberDeck builders!
## HyperPixel 4 Rectangular Rotations
Ensure rotation is set to "Normal" in "Display Configuration"
And that the dtoverlay is in `/boot/config.txt`:
```
dtoverlay=vc4-kms-dpi-hyperpixel4
```
Finally use one of the following `dtparam` lines immediately underneath to set the parameters:
* The default is portrait with header on the right, no extra line needed
* `dtparam=rotate=90,touchscreen-swapped-x-y,touchscreen-inverted-y` - Landscape with header on the bottom
* `dtparam=rotate=180` - Portrait with header on the left
* `dtparam=rotate=270,touchscreen-swapped-x-y,touchscreen-inverted-x` - Landscape with header on the top
## HyperPixel 4 Square Rotations
HyperPixel 4 Square does not correctly swap or invert touch input, so you may want to use the Xorg config method below.
Ensure rotation is set to "Normal" in "Display Configuration"
And that the dtoverlay is in `/boot/config.txt`:
```
dtoverlay=vc4-kms-dpi-hyperpixel4sq
```
Finally use one of the following `dtparam` lines immediately underneath to set the parameters:
* Default is header on the top
* `dtparam=rotate=90` - Header is on the left (wonky touch, see below)
* `dtparam=rotate=180` - Header *still* on the top (doesn't work? Same as default)
* `dtparam=rotate=270` - Header is on the right (wonky touch, see below)
:warning: The `touchscreen-swapped-x-y` parameter does not seem to work with Square. You may need to use the script below for Raspberry Pi OS with Desktop.
## On the fly rotation
Rotating the display via "Screen Configuration" ("arandr") results in inverted touch input and other weirdness- use the dtoverlay params.
If you want to rotate on the fly you can use the below bash script to rotate either display and persist settings into Xorg configuration files.
:warning: Note: You *must* remove the `rotate=` argument from `/boot/config.txt` for these to make sense.
You can remove the rotation config by deleting the `/usr/share/X11/xorg.conf.d/88-hyperpixel4-touch.conf` and `/usr/share/X11/xorg.conf.d/88-dsi-1-rotate.conf` files.

The post says you only need this one line in your config.txt, but it really means is you need to keep /boot/config.txt completely untouched, apart from adding this to the very bottom:
dtoverlay=vc4-kms-dpi-hyperpixel4
Hope that helps.
Edit: Leave the existing dtoverlay line in place too, don’t remove it or comment it out.
Ok everything is back to redone! ran the pi 4 installer and added the dtoverlay at the end of config.txt

Still NO HYPER PIXEL DISPLAY!!!
Hmm, nope, you’ve added a lot more than just the single line I suggested. To repeat - keep the config.txt file completely vanilla and just add this single line at the bottom:
dtoverlay=vc4-kms-dpi-hyperpixel4
I did only add the one line. The install added everything else
If you read the linked announcement - “users running the latest and greatest Raspberry Pi OS should forego our installer …”
The extra lines are coming from the installer, that you no longer require. I imagine they are tripping things up.
So do a clean os install and just add that line? Don’t do anything from get hub?
That’s what the PSA linked above says. Also contains info about rotations, and I would highly recommend you read it and then proceed.
ok did a clean fresh OS install and added only
